Disclosed is a needle tapping machine for stimulating hair growth, comprising a needle tapping head (1), two elastic current-conducting plates (4) and a handle (5). The needle tapping head (1) comprises a housing (10), a circuit board (11) and multiple silicon rubber columns (3), wherein the circuit board (11) is located in the housing (10), and the silicon rubber columns (3) are inserted into through holes set on the obverse side of the housing (10) and the columns are electrically connected with the circuit board (11) via conductive springs (12). One end of the elastic current-conducting plates (4) is fixed on the housing (10) and the other end is fixed on the handle (5) with a pulse circuit module (51) set in the handle (5). The pulse circuit module (51) is electrically connected with the circuit board (11) via the elastic current-conducting plates (4). During treatment, the silicon rubber columns (3) and a tapping needle (2) are used to tap and puncture that part of the scalp with hair loss with a reciprocating motion thus that part of the scalp with hair loss receives effective stimulation, and simultaneously, since the silicon rubber columns (3) are in action, the pulse circuit module (51) automatically adjusts to emit pulse waves to stimulate the pallium and activate cells, depending on factors such as the strength of contact and arousal, etc., thereby realizing the goal of promoting hair re-growth.Linvention concerne un appareil à percussion doté daiguilles destiné à stimuler la croissance des cheveux, comprenant une tête (1) de percussion dotée daiguilles, deux plaques (4) élastiques conductrices de courant et une poignée (5). La tête (1) de percussion dotée daiguilles comprend un logement (10), une carte (11) de circuit imprimé et de multiples colonnes (3) en caoutchouc de silicium, la carte (11) de circuit imprimé étant située dans le logement (10), et les colonnes (3) en caoutchouc de silicone étant insérées dans des orifices de passage situés sur le côt
